Population III stars are the first generation that formed in the Universe, made from pristine hydrogen and helium, without any heavier “metals.” They’re difficult to find, surrounded by the early

An unfolding mystery is how early supermassive black holes got so big, so early. Their high mass is tough to explain through a ladder of mergers; instead, astronomers suggest they
Astronomers have uncovered a vast cloud of energetic particles—a “mini halo”—surrounding one of the most distant galaxy clusters ever observed, marking a major step forward in understanding the hidden forces
The search for life beyond our planet continues, and one of the most underappreciated tools in an astrobiologist’s toolkit is statistics. While it might not be as glamorous as directly
The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to
Detecting exoplanets is one thing, but imaging them is another thing entirely. Astronomers can detect them by the way they block their star’s light and by the way they make
This year’s $10,000 Schweickart Prize is going to a team of students who are proposing a panel to address the risks that could arise when we start tinkering with asteroids.
JWST is a powerful telescope and has directly observed a handful of exoplanets. But according to a new paper, it could set its sights higher, way higher. Astronomers suggest that
Space exploration enthusiasts tend to overlook the regulatory aspects of their desired goals. They focus on technologies and the science we can do with them rather than mundane things like
Most meteorites that have reached Earth come from the asteroid belt between Mars and Jupiter. But we have 1,000 or so meteorites that come from the moon and Mars. This
